The present paper discusses three Japanese species of Pteromalidae reared from cocoons of the rice beetle Oulema oryzae (Kuwayama, 1929) (Coleoptera, Chrysomelidae). Pteromalus cyclostomus Ishizaki sp. nov. is described. Spaniopus monospilus (Thomson, 1878) and Usubaia liparae Kamijo, 1983 are newly recognized as parasitoid wasps of O. oryzae , and the former is also recorded from Japan for the first time. Pteromalus bifoveolatus Förster, 1861 is also newly recorded from Japan, with a new host record from Samia cynthia pryeri (Lepidoptera: Saturniidae).  相似文献

Two new genera, Repkinella and Aristotreta, and five new species from the class Lingulata (Brachiopoda) are described from the Upper Cambrian olistolith limestone enclosed in the Upper Ordovician olistostrome from the Agyrek mountains (northeastern Kazakhstan). The family Curticiidae Walcott et Schuchert is referred to the order Lingulida, not order Acrotretida, where it was previously placed.  相似文献

Neohydrocoptus jaechi (Wewalka) is recorded for the first time in Egypt. It is very similar to N. angolensis (Peschet), but there are aedeagal differences. The karyotype consists of 6 pairs of autosomes and sex chromosomes which are neo-XY (♂) and neo-XX (♀). C-banding shows that the sex chromosomes of Canthydrus diophthalmus (Reiche & Saulcy) are not the small pair suggested by Bilton (1992), but are one of the largest pairs, with the Y-chromosome totally heterochromatic. The implications of these findings are considered in the light of Belkaceme's (1991) work on the phylogeny of Noteridae. Neohydrocoptus is placed among the group of more primitive genera, outside the closely-knit group of higher Noteridae, while Canthydrus is placed right at the top of the higher Noteridae. The neo-XY sex chromosomes of Neohydrocoptus could be a primitive condition for the family, while the system found in Canthydrus is derivable from that of Synchortus Sharp (Saleh Ahmed et al., 1997) (one of Belkaceme's basal genera of the higher Noteridae) by loss of the mainly heterochromatic X2-chromosome, leaving the more normal X1-chromosome and the Y, which is almost entirely heterochromatic in Synchortus and completely so in Canthydrus.  相似文献

Three species of Xerolycosa: Xerolycosa nemoralis (Westring, 1861), Xerolycosa miniata (C.L. Koch, 1834) and Xerolycosa mongolica (Schenkel, 1963), occurring in the Palaearctic Region are surveyed, illustrated and redescribed. Arctosa mongolica Schenkel, 1963 is removed from synonymy with Xerolycosa nemoralis and transferred to Xerolycosa, and the new combination Xerolycosa mongolica (Schenkel, 1963) comb. n. is established. One new synonymy, Xerolycosa undulata Chen, Song et Kim, 1998 syn.n. from Heilongjiang = Xerolycosa mongolica (Schenkel, 1963), is proposed. In addition, one more new combination is established, Trochosa pelengena (Roewer, 1960) comb. n., ex Xerolycosa.  相似文献

Apterous viviparous females of Neoamphorophora ledi (Wahlgren, 1938) living on Rhododendron degronianum Carr. (Ericaceae) on Honshu island, Japan, are redescribed and the hitherto unknown alate viviparous females are here described. Rhododendron degronianum is a new host plant species for this aphid. This species is recorded for aphid fauna of Eastern Palearctic for the first time. Keys to species of Neoamphorophora based on apterous and alate viviparous females are given. A key to aphid genera with swollen siphunculi living on species of Rhododendron worldwide based on apterous viviparous females is also provided.  相似文献
